Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention;

As used herein, the term "identification code image" means an image such as a product number, a barcode or a QR code to which the identification code image is attached. In the present invention, when the identification code image is attached to a specific object (for example, goods, paper, etc.) by inserting authentication information into the identification code image, the identification code imager is genuine using the authentication information inserted in the identification code image. I could prove it.

As used herein, "authentication information" is information used to confirm the authenticity of a product to which an identification code image is attached, and may include a code number of a product, an authentication number, and the like.

1 is a network diagram illustrating a system for generating an identification code image according to an embodiment of the present invention.

Referring to FIG. 1, the identification code image generating system includes an identification code image generating apparatus 100 and an object authenticity checking apparatus 200.

The identification code image generating apparatus 100 is an apparatus for generating the identification code image 300 by inserting authentication information into the identification code image 300.

For example, the identification code image generating apparatus 100 may generate the identification code image 300 by inserting authentication information into a barcode image. The barcode image may be inserted into a specific object (gift certificate, lotto, sneaker, etc.), and the authentication information inserted in the barcode image may be used to prove that the barcode imager is genuine.

To this end, the identification code image generating apparatus 100 determines a specific region of the identification code image (eg, a barcode image, a QR code image, etc.) 300 as an authentication information insertion region. For example, the identification code image generating apparatus 100 may determine a blank portion of the identification code image 300 as the authentication information insertion region.

Then, the identification code image generating apparatus 100 inserts the authentication information in the authentication information insertion area of the identification code image 300. In this case, the identification code image generating apparatus 100 may generate a plurality of pixel spaces consisting of a plurality of points according to a binary code corresponding to the authentication information, and insert the plurality of pixel spaces into the authentication information insertion region.

For example, the binary code corresponding to the object authentication information to which the identification code image 300 is to be attached is 1011, the pixel space corresponding to 1 is defined as 4 points, and the pixel space corresponding to 0 is 8 If it is defined as a point, the identification code image generating apparatus 100 generates a pixel space of four points, a pixel space of eight points, a pixel space of four points, and a pixel space of four points. Can be inserted into the authentication information insertion area of the image.

In this case, the identification code image generating apparatus 100 generates a binary code by binarizing each of the characters constituting the object authentication information to which the identification code image 300 is attached or to the object authentication information to which the identification code image 300 is attached. The corresponding binary code may be predefined.

Accordingly, the identification code image generating apparatus 100 determines whether the binary value of each binary code is 1 or 0, generates a pixel space composed of a predetermined number of dots corresponding to each of the identification code images 300, and authenticates the identification code image 300. It can be inserted in the information insertion area.

That is, since the binary code corresponding to the authentication information can be represented by changing only the size of the pixel space indicating 0 and 1, even if the binary code is long because the size of the authentication information is large, the authentication information of the identification code image 300 is recognized. The advantage is that it can be inserted in the insertion area.

As such, the identification code image generating apparatus 100 expresses the binary codes corresponding to the authentication information in pixel spaces having different sizes and inserts them into the authentication information insertion region of the identification code image 300, thereby identifying the identification code image 300. The user using the object attached to the identification code image 300 by scanning the identification code image 300 attached to the object by using the device authenticity check device (for example, smart phone, etc.) that they hold Using the authentication information inserted in the identification code image 300 has the advantage that it is possible to immediately check the authenticity of the inserted object. Hereinafter, the object authenticity checking apparatus 200 will be described.

The object authenticity checking apparatus 200 scans an identification code image 300 attached to a specific object according to a user's manipulation, extracts the pixel space inserted into the code image, and analyzes the pixel space to indicate the pixel space. Information can be extracted.

That is, when the object authenticity checking apparatus 200 extracts pixel spaces of different sizes from the identification code image 300, the binary value is determined according to the number of points of the pixel spaces by referring to the binary value table for each pixel space. Determine. More specifically, the object authenticity checking apparatus 200 may determine whether a binary value corresponding to the pixel space is 0 or 1 based on the number of points in which the pixel space is configured by referring to a predetermined binary table for each pixel space. . Then, the object authenticity check apparatus 200 determines a binary code by sequentially combining binary values.

For example, when one pixel space consisting of four points and six pixel spaces consisting of eight points are extracted from the identification code image 300, the object authenticity checking apparatus 200 may determine the pixel space consisting of four points. Recognizes as 1, the pixel space of 8 points is recognized as 0 to generate the binary code "1000000".

For example, if two pixel spaces consisting of six points and three pixel spaces consisting of eight points are extracted, the object authenticity checking apparatus 200 recognizes the pixel space consisting of six points as 1, and 8 The pixel space consisting of two dots is recognized as 0 to generate a binary code "11000".

Thereafter, the apparatus 200 for verifying authenticity of the object extracts authentication information corresponding to the binary code by referring to the authentication information table for each binary code, and verifies whether the specific object is authentic according to whether the authentication information and the information associated with the specific object are the same. You can check.

In this way, the user extracts the authentication information inserted in the identification code image 300 by simply scanning the identification code image 300 by using the object authenticity check device 200 held by the user, and identifies the identification code image. The authenticity of the object to which the 300 is attached can be checked.

Referring to FIG. 2, the identification code image generating apparatus 100 may include an authentication information insertion region determiner 110, a pixel space generator 120, an image generator 130, and a controller 140.

The authentication information insertion area determiner 110 may determine an authentication information insertion area in which the authentication information is to be inserted in the identification code image. In this case, the authentication information insertion area determiner 110 may determine the blank portion of the identification code image as the authentication information insertion area.

The pixel space generator 120 generates a pixel space based on a binary code corresponding to authentication information of an object to which the identification code image is attached. In this case, the pixel space generation unit 120 may generate pixel spaces of different sizes consisting of a plurality of points based on a binary code corresponding to the authentication information.

In other words. The pixel space generation unit 120 may generate a pixel space composed of a predetermined number of points corresponding to each of the binary values by determining whether the binary value is 1 or 0 with reference to the previously constructed pixel space DB.

For example, when the binary code corresponding to the authentication information “AABBCC” is 100000, the pixel space generation unit 120 includes one pixel space including a predetermined number of points corresponding to 1 and a predetermined number corresponding to 0. You can create five pixel spaces of points.

The image generator 130 inserts the plurality of pixel spaces generated by the pixel space generator 120 into the authentication information insertion region to generate an identification code image into which the authentication information is inserted. In this case, although the plurality of pixel spaces generated by the pixel space generation unit 120 are expressed in invisible colors of the user, the object authenticity checking device scanning the identification code image extracts the plurality of pixel spaces by scanning them. I could do it.

The controller 140 may control other components of the identification code image generating apparatus 100 to generate an image into which data is inserted.
